Emissions Report 2022

Study 2: Extended tieback with existing pipelines Tieback: 100-km subsea tieback with two injection wells.

Assumption: An existing pipeline was available for use and electro-hydraulic Christmas trees were in operation. The chemical injection would mainly be for start-up and shut down. A key point demonstrated through this study is that the cost of the WEC and energy storage solution is independent of tieback distance, contributing to significant cost savings for umbilicals over long distances. Cost saving: More than 80%, about £94mn. CO 2 reductions: 92%, the equivalent of removing 2000 cars from UK roads for a year. The lead time would also be greatly reduced when using the complete system over the umbilical, decreasing from 24 months to 12 months. Cost saving: More than 80%, about £94mn.

The ever-growing role of the supply chain

So from now on, reducing emissions will entail overcoming engineering challenges. But this also presents an opportunity to the supply chain and operators. As the focus on emissions performance has grown, so too have expectations concerning a company’s environmental, social and governance (ESG) performance. To this end, the supply chain has a role in servicing the offshore assets with technologies and value offering that cut emissions. Over the last few years, our supply chain membership’s value offering has grown to service all parts of the oil and gas lifecycle. Operating safe and reliable assets will continue to be a key focal point of the industry but emission reduction technologies are growing in importance.

This report devotes more focus to installations and terminal emissions which contribute around 90% of emissions. However, reductions in these areas tend to lead to smaller emissions from the supply chain, which is looking at innovative technologies, revised engineering methods and collaboration in order to lower emissions. To date, industry has cut its emissions by executing operational improvements and running a plant more efficiently. However, these gains have by now mostly been extracted.
